JOHN W. HARMON, OF CRESTON IOWA.

RIDING-HARROW.

To all whom it may concern:

Be it lmown that I, J OHN W. HARMON, a citizen of the United States, residing at Creston, in the county of Union and State of Iowa, have invented a certain new and useful Riding-Harrow, of which the followmg is a specification.

The object of my invention is to provide a riding harrow, simple, durable and inexpensive in construction, and soarranged as to afford a seat for the operator, above and ahead of the dust arising from the harrow, and so designed as to distribute the weight of the platform and operator evenly on the harrow sections.

A further object is to provide a riding harrow in which the operator may quickly and easily shift his position during the use of the harrow, to thereby increase or decrease the weight on the harrow sections.

A further object is to provide a riding harrow which adapts itself to the irregular motion of the harrow sections as it is advanced over the ground.

A further object is to provide a riding harrow arranged with adjustable rods for securing the harrow sections in thelr correct positions relative to the truck, to thereby readjust the harrow sections to make their teeth travel in the proper paths.

A further object is to provide av riding harrow in which a tongue is used to prevent the draft animals from becoming tangled in the harrow sections.

A further object is to provide a riding harrow in which the truck section may be detached and used in connection with a disk or other farm implement.

My invention consists in the construction, arrangement, and combination of the various parts of the device whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which Figure 1 shows a side elevation of the complete riding harrow. Fig. 2. shows a front elevation of the same. Fig. 3 shows a top plan view of the same. Fig. 4 shows a detail, sectional view taken on the line 4-4 of Fig. 1. Fig. 5 shows adetail view showing the pivoted bars for equalizing the weight of the truck on the harrow sections. Fig. 6 shows a detail, sectional view taken on the line 66 of Fig. 2. Fig. 7 shows a Specification of Letters Patent.

vReferring to the accompanying drawings, the reference numeral 10 indicates the truck axle mounted on the wheels 11 which supports the tongue 12 and also the upwardly extended, supporting bar 13. The brace rods 14 are fixed to the rear outer ends of the axle 10 at one end and are connected to the tongue 12 at the other. A rearwardly extending plate 15 and a bracket 16 are pivoted, by means of the bolt 17 to the upwardly extended bar 13 as shown in Figs. 1, 2 and 4 of the drawings. A grooved wheel 17 is rotatably mounted in the bracket 16. The harrow teeth 18 are mounted in the cross pieces 19 which are pivotally connected to the longitudinally extended strips 20. The hooks 20 are fixed to the said strips 20 and are attached to the eyes 20 in the draw bar 21. The upwardly extended bars 22 are fixed to the cross pieces 19 and support the bar 23 which is pivotally connected to each of the upwardly extended bars 22. The levers 24 are mounted on the rear cross pieces 19 and are pivoted near their lower ends to the bars 23, said levers 24 being provided with spring-actuated pawls 25, and said pawls being arranged to engage sectors 26 fixed to the bars 23, as shown in Fig. 1. A supporting bar 27 with an outwardly projecting flange 28 thereon is fixed to the central bar 23 by means of the clamp bar 27 and bolts 27*, as shown in Fig. 5, and supports the clips 29 which are pivotally mounted thereon.

The upwardly and forwardly extended bars 30 are fixed to the central bars 23 of the outer harrow sections on which are suspended the links 31. The beams 32 are connected to the links 31 at one end and are pivotally mounted in the clips 29 at the other. The threaded rods 33 are fixed near the top of the uprights 34 which are pivotally connected to the beams 32 and support the cross beam 35. The positions of the uprights 34 on the beams 32 are such that the weight of the driver and of the truck platform is evenly distributed between the different harrow sections. The truck platform 36 is supported at its rear end by the cross beam 35 and at its forward end by the rod 36 which is fixed thereto and which is mounted in the grooved wheel 17*. The bolt 37 in the bracket 16 is arranged to prevent the rod 36 from becoming disengaged from the grooved wheel. 17. The uprights 38 are fixed to the outer edgesof the truck platform 36 and support the cross rods 3-), the rear uprights being braced by the brace rods 41:0. A seat .4-1. is fixed to the cross piece 12, said cross piece being slidingly mounted on the cross rods 39 by means of the upwardly extended hooks $3. The rods at are adjustably connected to the draw bar 21 at one end and are connected to the plate 15 at the other end by means of the books 45. By adjusting these rods 41-1; the barrow teeth may be shifted so they will not track as the harrow is drawn forwardly. The rod to is fixed. to the draw bar 21 at one end and detachably connected to the hook $7 at the other end which mounted on the axle 10, as shown in Fig. 7

In the practical operation of the device, the driver first adjusts the teeth in the harrow section, and then occupies the movable seat on the platform. As the ground is traversed the driver slides his seat forwardly or rearwardly to apply more or less weight on the ha rrow sections as the condition of the ground requires. The equalizing bars automatically distribute the weight to the different harrow sections. and the roller on the truck forms an adjustable bearing for the seat sum'iorting platform, which is moved slightly forwardly and rearwardly by the unsteady motion of the harrow sections and evening bars.

I claim as my invention:

1. I11 a device of the class described, the combination of a harrow section, a truck in front of said harrow section. a platform supported at its forward end on said truck and at its rear end on said harrow section, supporting standards rising at each side of the platform, a pair of parallel bars sup ported longitudinally on said standards. a transverse member suspended from. and between said bars and adapted to slide thereon, and a seat supported by said member,.
